Specifically, a first handle state of the outer handle is obtained while the operation instruction is obtained, and if the first handle state is different from the target handle state, the execution motor is controlled to rotate towards the target handle state; as an example, if the target handle state corresponding to the operation instruction is the unfolding state, determining whether the handle state (i.e. the first handle state) of the outer handle is the unfolding state at the moment, and if not, controlling the execution motor to rotate forwards; if the handle state of the outer handle is the unfolding state, no operation is executed.
And then, in the rotation process of the execution motor, acquiring a first real-time rotating speed of the execution motor and a first real-time handle state of the outer handle, and when the first real-time rotating speed of the execution motor is not equal to a preset target rotating speed, adjusting the rotating speed of the motor to the preset target rotating speed, wherein the first real-time rotating speed of the motor can be adjusted to the preset target rotating speed by adopting speed adjusting methods such as voltage regulation, speed regulation, frequency conversion, speed regulation and the like. And controlling the execution motor to stop rotating until the first real-time state of the outer handle reaches the target handle state.
According to the invention, in the rotating process of the outer handle, the speed is fed back in real time, and the rotating speed of the executing motor is constantly equal to the set target rotating speed by adopting speed regulating methods such as voltage regulation, frequency conversion, speed regulation and the like according to the load of the motor, so that the expansion or reset of the outer handle is not influenced by the external load, and the user experience is improved.
Example two
As shown in fig. 2, a control flow chart of a control method of an external handle of an automobile according to the present invention includes:
step S201: acquiring an operation signal and a finished vehicle state;
the operation signals come from a capacitance induction switch arranged on the outer handle and a central control switch arranged in the vehicle;
when the operation signal from the capacitance induction switch is obtained, information authentication is carried out on the operation signal;
step S202: judging whether the state of the whole vehicle reaches the operating condition of the operating signal, and if so, sending a corresponding operating instruction, specifically: the operation signals comprise unfolding signals and resetting signals;
when the operation signal is the unfolding signal, the target handle state is an unfolding state, and the corresponding operation conditions include: the vehicle speed is less than the first vehicle speed;
when the operation signal is the reset signal, the target handle state is a reset state, and the corresponding operation conditions include: the vehicle speed is greater than the second vehicle speed or the gear is a D gear;
step S203: acquiring the operation instruction and a first current handle state of the outer handle, wherein the operation instruction corresponds to a target handle state, and the handle state at least comprises a spreading state and a resetting state;
step S204: controlling an execution motor to rotate according to the operation instruction and the first current handle state, and driving the outer handle to rotate towards a target handle state;
step S205: acquiring a first real-time rotating speed of the executing motor and a first real-time handle state of the outer handle;
step S206: adjusting the first real-time rotating speed to be equal to a preset target rotating speed; and simultaneously judging whether the first real-time handle state of the outer handle reaches a target handle state corresponding to the operation instruction or not, and controlling the execution motor to stop rotating if the first real-time handle state of the outer handle reaches the target handle state.
Before executing an operation instruction, an operation signal is obtained, the operation signal comes from a capacitance induction switch arranged on the outer handle and a central control switch arranged in the vehicle, and the capacitance induction switch and the central control switch are triggered by a driver to send out the operation signal.
Specifically, the capacitance induction switch is arranged on the outer handle, a driver holds the induction key to be close to the vehicle body, and when the capacitance induction switch on the outer handle is pressed, an operation signal is sent out; the central control switch is arranged in the vehicle body, a driver presses the central control switch on the driver seat, and the central control switch sends out an operation signal.
Because the operation signal sent by the capacitance induction switch is sent by the induction key, the expansion and the reset of the outer handle can be controlled only by the correct induction key, so that the information authentication needs to be carried out on the operation instruction from the capacitance induction switch, the operation signal is valid if the information authentication is correct, and the operation signal is invalid if the information authentication is wrong, and the subsequent operation is not executed.
Further, after an operation signal controlled by a driver is acquired, whether the state of the whole vehicle is suitable for executing the operation signal is judged, and if the state of the whole vehicle does not meet the operation condition, the operation is not executed.
Specifically, the vehicle needs to be in a locked state when the outer handle is unfolded, that is, the vehicle speed should be equal to 0km/h, and naturally, when the vehicle speed tends to 0km/h but is not equal to 0km/h, the outer handle can be unfolded in advance, so that certain errors are allowed in the vehicle speed, and the judgment condition is that the vehicle speed is small and the first vehicle speed is preferably 0.1 km/h.
When the vehicle is in an unlocked state when the outer handle is reset, and when the vehicle speed is greater than a second speed or the gear is in a D-gear forward gear, wherein the second speed is preferably 5km/h, the vehicle can be judged to be in the unlocked state.
After the determination, if the vehicle state reaches the corresponding operating condition, the corresponding operating instruction is sent out, and the execution process of the operating instruction is the same as that in the first embodiment, which is not described herein again.
After receiving the operation signal sent by the subjective idea of the driver, the invention judges the correctness of the operation signal, and prevents the misoperation of the outer handle from influencing the driving safety; and in the rotating process of the outer handle, the speed is fed back in real time, and the rotating speed of the actuating motor is constantly equal to the set target rotating speed by adopting speed regulating methods such as voltage regulation, frequency conversion, speed regulation and the like according to the load of the motor, so that the expansion or reset of the outer handle is not influenced by the external load, and the user experience is improved.

step S305: adjusting the first real-time rotating speed to be equal to a preset target rotating speed; and meanwhile, judging whether the first real-time handle state of the outer handle reaches the unfolding state or not, and controlling the execution motor to stop rotating if the first real-time handle state of the outer handle reaches the unfolding state.
Specifically, when the vehicle is collided from the outside, the driver does not need to send an operation signal, and an operation instruction for unfolding the outer handle is automatically sent out and the outer handle is unfolded, and the unfolding process of the outer handle is the same as that of the first embodiment, and is not described herein again.
When the vehicle is collided, the outer handle is automatically unfolded without manually sending an operation signal, so that rescue workers can conveniently open the vehicle door for rescue, and the safety of the outer handle is improved.
Example four
As shown in fig. 4, a control flow chart of a control method of an external handle of an automobile according to the present invention includes:
step S401: acquiring an operation instruction and a first current handle state of an outer handle, wherein the operation instruction corresponds to a target handle state, and the handle state at least comprises a spreading state and a resetting state;
step S402: controlling an execution motor to rotate according to the operation instruction and the first current handle state, and driving the outer handle to rotate towards a target handle state;
step S403: if the power is cut off in the rotation process of the executing motor, executing steps S404-S406 after next power-on;
step S404: acquiring a second current handle state of the outer handle, and if the second current handle state is in a middle state, controlling the execution motor to rotate and driving the outer handle to rotate towards an unfolding state;
step S405: acquiring a second real-time rotating speed of the executing motor and a second real-time handle state of the outer handle;
step S406: adjusting the second real-time rotating speed to be equal to the preset target rotating speed; and controlling the execution motor to stop rotating when the second real-time handle state of the outer handle is judged to reach the unfolding state.
Specifically, if the power failure occurs in the process of unfolding or resetting the outer handle by the execution motor according to the operation instruction, the state of the outer handle is automatically detected after the power is turned on, and the outer handle is unfolded. In most cases, the driver leaves the vehicle when the outer handle is not reset, so that the outer handle is powered off in the intermediate state, and when the vehicle is powered on next time, the driver generally opens the vehicle, and the outer handle is automatically unfolded at the moment, so that the driver can conveniently open the vehicle door. The process of unfolding the outer handle is the same as that of the first embodiment, and is not described herein.
The invention sets a processing method of abnormal power failure, thereby avoiding the influence on use caused by the fact that the outer handle is always in a middle state; and in the rotating process of the outer handle, the speed is fed back in real time, and the rotating speed of the executing motor is constantly equal to the preset target rotating speed by adopting speed regulating methods such as voltage regulation, frequency conversion, speed regulation and the like according to the load of the motor, so that the expansion or reset of the outer handle is not influenced by the external load.
EXAMPLE five
As shown in fig. 5, a control flow chart of a control method of an external handle of an automobile according to the present invention includes:
step S501: acquiring an operation instruction and a first current handle state of an outer handle, wherein the operation instruction corresponds to a target handle state, and the handle state at least comprises a spreading state and a resetting state;
step S502: controlling an execution motor to rotate according to the operation instruction and the first current handle state, and driving the outer handle to rotate towards a target handle state;
step S503: acquiring a first real-time rotating speed of the executing motor and a first real-time handle state of the outer handle;
step S504: adjusting the duty ratio of an input voltage signal of the execution motor according to the difference value of the first real-time rotating speed and a preset target rotating speed so as to enable the first real-time rotating speed to be equal to the preset target rotating speed;
if the first real-time rotating speed is less than the preset minimum rotating speed within the set time, disconnecting the power supply of the executing motor;
and simultaneously judging whether the first real-time handle state of the outer handle reaches a target handle state corresponding to the operation instruction or not, and controlling the execution motor to stop rotating if the first real-time handle state of the outer handle reaches the target handle state.
Specifically, the rotation of the execution motor is controlled according to the operation instruction and the first real-time handle state of the outer handle, and in the rotation process of the execution motor, the control of the rotation speed of the execution motor is as shown in fig. 6: the real-time rotating speed of the executing motor is fed back through the rotating speed sensor, when the real-time rotating speed of the executing motor is not equal to the preset target rotating speed, the duty ratio of an input voltage signal of the executing motor is adjusted, namely the input voltage and the input power of the executing motor are adjusted by adopting a PWM (pulse-width modulation) speed regulation principle, so that the real-time rotating speed is adjusted to the preset target rotating speed, and the executing motor is controlled to stop rotating until the state of the outer handle reaches the target handle state.
The PWM speed regulation is to control the on-off of the switch device of the inverter circuit, so that a series of pulses with equal amplitude are obtained at the output end, and the pulses are used for replacing sine waves or required waveforms. That is, a plurality of pulses are generated in a half cycle of an output waveform, the equivalent voltage of each pulse is a sine waveform, the obtained output is smooth, low-order harmonics are few, and the width of each pulse is modulated according to a certain rule, so that the magnitude of the output voltage of the inverter circuit can be changed, and the output frequency can also be changed.
In addition, an execution motor protection mechanism is further arranged in the embodiment, if the first real-time rotating speed of the execution motor is not adjusted to the target rotating speed within the set time and is always smaller than the set preset minimum rotating speed, the load of the execution motor is too large, the rotating speed cannot be adjusted to the target rotating speed through PWM speed regulation, and at the moment, in order to prevent the execution motor from being damaged by dry burning, the power supply of the execution motor is disconnected. Wherein the minimum rotation speed is a rotation speed tending to 0rpm, and is set according to the specification of the actuating motor. It should be noted that the motor protection mechanism in this embodiment is not limited to the case of using PWM speed regulation, but is also applicable to other motor speed regulation modes.
The invention adopts PWM speed regulation to realize the regulation of the rotating speed of the actuating motor, and adopts a digital mode to control an analog signal, thereby greatly reducing the cost and the power consumption; and an executing motor protection mechanism is arranged, so that the executing motor is prevented from being damaged by dry burning when the load is overlarge.
